Embodiment Construction

[0067] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0068] figure 1 According to the network topology diagram in this embodiment, in the network topology diagram, the main network nodes form a completely distributed flat peer-to-peer network structure through self-organization. When the network is successfully constructed, each node is responsible for neighbor discovery and maintenance. Generate a neighbor table. The nodes in the network elect the current "virtual center" as the control node through the self-organizing election strategy, and at the same time elect the candidate "virtual center" node. When the current control node fails, the next control center can be quickly generated. The election strategy adopts the distributed super node election algorithm DSNE.

Abstract

The invention discloses a distributed ad hoc network architecture with a virtual center based on a dynamic topology of a mobile agent, and aims at the characteristics that the network size is large and the geographic distances of node distribution are far in a high-speed mobile environment, the communication link bandwidth is small, the node movement is fast, the damage is easily caused and the like, and interconnection of information between nodes of a wireless sensor network in a special extreme environment are guaranteed. On the basis of a distributed ad hoc network, the thought of an SDN (software defined network) is fused, and the distributed architecture containing the virtual center is constructed. Meanwhile, the distributed ad hoc network architecture aims at the characteristic ofhigh maneuverability of the wireless ad hoc network, adopts real-time topology sensing and control based on the mobile agent, and combines a plurality of terminals organically through a wireless ad hoc network technology. A rapid topology sensing and control algorithm of the mobile agent based on an ant colony algorithm and pheromone concentration is designed to be fully adapted to the wireless adhoc network in a high maneuvering environment.

Description

technical field [0001] The invention belongs to the field of ad hoc networks, and specifically relates to the networking technology and principle of ad hoc networks. Background technique [0002] With the rapid development of modern information technology, the military communication field is also triggering a new wave of change. People are constantly proposing new combat theories and combat methods in response to the rapid development of communication technology. Many experts predict that the future battlefield will be digital. battlefield. Under the conditions of informatization, the construction of a digital battlefield under the condition of information has the main requirements for wireless communication networks: no need to rely on fixed basic network facilities, rapid deployment, strong invulnerability; Business needs to meet the requirements of "communication in motion and real-time communication" in mobile operations; it can realize the seamless link of tactical and...
